AUTOMOBILE-TIRE Application filid May 28, 1913.

To all whom it may mil-wow.

Be it known that l, Cir-times Kinnxva, a citizen of the linitml Slates, residing at Burchard, in the enmity of Pawnee, State of Nebraska, ha e in vented certain new and useful Improvements in Antomobile-Tires; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to automobile tires.

The object of the invention resides in the provision of an automobile tire which may be used in lieu of a pneumatic tire for the purpose of avoiding the disadvantage of punctures and which will etliciently absorb the shocks and jars incident to travel.

\Vith the above and other objects in view the invention consists in the details of construotion and in the arrangen'ient and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claim.

In describing the invention in detail ref erence will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views, and in WhlCl1 Figure 1 is a side elevation of a fragment of an automobile wheel having the improved tire associated therewith; Fig. 2, a section on the line 2-2 of Fig. 1; Fig. 3, a section on the line 3-3 of Fig. 1; Fig. 4, a detail perspective view of a fragment of one of the rings with which the terminals of the springs interlock; Fig. 5, a detail perspectue View of one of the springs, and Fig. (3, a view of the blank from which each spring is formed.

Referring to the drawings 10 indicates the hub of an automobile wheel from which radiate spokes 11. Supported upon the outer ends of the spokes 11 is a rim or folly 12 and surrounding this rim or telly is a tlre 13. Disposed against respectwe sides of the rim or telly 12 are annular plates 14 which are secured in place by rivets 15 passing through said plates and through the rim or felly 12. Formed in the outer sides of each of the plates 14 are radially disposed recesses 16 for a purpose that will presently appear. The tire further comprises a plurality of springs A each of which is formed from a metal blank bent into substantially circular shape and having its cation. of Letters Patent.

free ends bent outwardly in spa ed as at 1? and 1S. llfh iree ends 1 are provided with inwardly directed str ck up portions 19 and 20. The normal it tance between the ends it? and 13 ot earl spring is less than the combined width of the plates 1-1 and telly 12. In applying the springs A the ends 17 and 18 are spread apart and positioned in embracing; rel lion to the plates 14- and telly 12 and the sun-cl; up portions 19 and 20 are brought into registration with recesses 16 of respective plates 14: when the tendency of the ends 17 and 18 to move together Wlll cause the struck up portions 19 and 20 to snap into respective recesses 10. In this manner the springs A are applied until the rim 12 is entirely surrounded and continuous spring tread tor the tire formed. Disposed against the ends 17 of the springs A is a locking plate 21,while corralendimy locking plate 29 is disposed against the ent s 18 of said spring. Disposed betwern adjac nt spokes l1 and embracing the plates 21 and spring ends 17 and 18, plates .lsland ri; .2 are U-shaped members including a bigot portion 23 and arms 2-1. he bight portion 23 of each of these U- sha iied 'llllltlS is provided with a trans verscly elongated bolt opening 25 through which is engaged a bolt 26 passing through the tire 13 and rim 12. Mounted in each of the arms 24 are set screws 27 which operate respectively against the plates 21 and to lock the various parts of the tire together as will to obvious. It Will be hotel that the elongated opening 25 permits if lateral movement of the U-shaped members when the set screws 27 are operated to force the plates 21 and 22 against respective ends 17 and 18 of the springs A.

From the foregoing construction it will be apparent that. it any one of the springs A should become broken the U-shaped incur her and locking plates 21 and 22 can be removed and a new spring applied, the en gagenient ot the struck up portions 19 and 20 in the rece, cs 16 serving o hold theren'iaining springs in place diiiring the application of a new spring for the broken one.

\Vhat I claim is:

A resilient tire comprising a rim, plates secured against each side of the rim and provided respectively with radial recesses in their outer sides, a plurality of arch leaf springs having their ends directed outwardly in spaced relation, inwardly directed portions struck up from the ends of said the latter into engagement with the spring in springs and engaging in corresponding reends.
